  • ICCE - Design of a smart greenhouse system based on MAPE-K and ISO/IEC-11179
    2018 IEEE International Conference on Consumer Electronics (ICCE), 2018
    Co-Authors: Young-duk Seo, Young-gab Kim, Euijong Lee, Kwangsoo Seol, Doo-kwon Baik
    Abstract:

    A smart greenhouse monitors the internal and external context information of the greenhouse in real time and keeps the internal environment in an optimal condition for the growth of crops. In this paper, we propose a smart greenhouse system based on MAPE-K that can automatically control the greenhouse. All information of the proposed system is stored and managed through an ontology knowledge repository based on ISO-IEC 11179 (Metadata Registry, MDR). Furthermore, we design a low cost smart greenhouse by interoperating the smart devices.

  • a design of Metadata Registry database based on object relational transformation methodology
    Journal of KIISE, 2015
    Co-Authors: Sooyoung Cha, Dongwon Jeong, Sukhoon Lee, Doo-kwon Baik
    Abstract:

    The ISO/IEC 11179 Metadata Registry (MDR) is an international standard that was developed to register and share Metadata. ISO/IEC 11179 represents an MDR as a metamodel that is an object model. However, it is difficult to develop an MDR based on ISO/IEC 11179 because the standard has no clear criteria to transform the metamodel into a database. In this paper, we suggest the design of an MDR data model that is based on object-relational transformation methodology (ORTM) for the MDR implementation. Hence, we classify the transformation methods of ORTM according to the corresponding relationships. After classification, we propose modeling rules by defining the standard use of the transformation. This paper builds the relational database tables as an implementation result of an MDR data model. Through experiments and evaluation, we verify the proposed modeling rules and evaluate the suitability of the created table structures. As the result, the proposed method shows that the table structures preserve classes and relationships of the standard metamodel well.

  • Ontology Integration Framework Based on XMDR
    Applied Mechanics and Materials, 2015
    Co-Authors: Jeong-dong Kim, Suk Hyung Hwang, Doo-kwon Baik
    Abstract:

    Ontology integration carries significant importance in terms of reuse of knowledge and interoperability. In this paper, a framework for ontology integration based on extended Metadata Registry plus (XMDR+) is focused, that is, we try to developer a methods for ontology integration to provide high quality Semantic Web services. To sum up, the ontology integration framework proposed herein not only produces global ontologies; but also defines such methods, and, thereby, performs better in extending and integrating ontologies. The framework will rely on a model independent of ontology storage structures, but will be capable of representing semantic relationships between different ontology systems.

  • XMDR+ : An Extended XMDR Model for Supporting Diverse Ontological Relations
    IEICE Transactions on Information and Systems, 2011
    Co-Authors: Jeong-dong Kim, Jiseong Son, Doo-kwon Baik
    Abstract:

    Metadata Registry (MDR) is based on the international standard ISO/IEC 11179. The committee of ISO/IEC JTC 1/SC 32, which had standardized the MDR, has started to improvise the MDR, and the improvised version is named extended MDR (XMDR). However, the XMDR does not fully support the ontology concept, and no method is available for mapping ontology registrations onto registries. To overcome the limitations of the outdated XMDR, this paper proposes an extended XMDR (XMDR+) framework. The XMDR+ framework provides a method for mapping of ontology registrations between the Metadata Registry and ontologies. To improve the functions of the XMDR, we have proposed herein a framework that is capable of defining a model that manages the relations not only among ontological concepts but also among instances, and guarantees the management and storage of their relationships for supporting valid relations of the ontologies.

  • NTMS - MMOR: A Mapping Method for Ontology Registration to Improve XMDR
    2011 4th IFIP International Conference on New Technologies Mobility and Security, 2011
    Co-Authors: Jeong-dong Kim, Jiseong Son, Doo-kwon Baik
    Abstract:

    The Metadata Registry (MDR) is based on the international standard ISO/IEC 11179. The committee of ISO/IEC JTC 1/SC 32, which standardized the MDR, revised it to an improved version named the extended MDR (XMDR). However, no method is available in XMDR to map ontology registrations onto registries. To overcome these limitations, this paper proposes a mapping method for ontology registration (MMOR). The MMOR provides a method to map ontological concepts onto Metadata registries. We propose herein a method that can define a mapping process and mapping roles between Web Ontology Language (OWL) constructs and Metadata Registry descriptions. The method guarantees semantic interoperability and facilitates flexibility of the Registry.

  • mcl query language for Metadata Registry access control
    Journal of the Korea Society of Computer and Information, 2009
    Co-Authors: Jinhyung Kim, Dongwon Jeong
    Abstract:

    In various fields, ISO/IEC 11179-based MDR (Metadata Registry) systems have been developed. However, the current systems do not observe the standard, so inconsistency issue between Metadata arises. Most of all, there exist several problems because ISO/IEC 11179 provides no standardized access method. SQL/MDR has been suggested to resolve those problems. SQL/MDR supports search operations, but it does not provide operations for vaild building and safe access for MDR. This paper, in the aforementioned issues, suggests MCL(Metadata Control Language) to guarantee safe and easy access control. MCL offers predefined roles and authority of user groups defined in ISO/IEC 11179 Part 6, and users are assigned to a proper user group. With such a way, MCL increases usability and security.

  • Implementation of the Metadata Registry-based Framework for Semantic Interoperability of Application in Ubiquitous Environment
    2007
    Co-Authors: Jeong-dong Kim, Dongwon Jeong, Jinhyung Kim, Doo-kwon Baik
    Abstract:

    Under ubiquitous environment, applications can gather and utilize various sensing information. There are many issues such as energy management, protocol standardization, independency on sensor fields, and security to be resolved for the complete ubiquitous computing. Especially, the independent information access in the sensor field is one of the most important issues to maximize the usability of sensors in various sensor fields. However, existing frameworks are not suitable for the ubiquitous computing environment because of data heterogeneity between data elements in sensor fields. Existing applications are dependent to sensor fields and sensors in the existing ubiquitous computing on environment is dependent to the application in the sensor field. In other word, an application can utilize just information from a specific sensor field. To overcome this restriction, many issues from a hardware or software view must be resolved. In this paper, we provide the design and implementation of the Metadata Registry-based framework (UbiMDR) of the Ubiquitous environment. This framework can provides the semantic interoperability among ubiquitous applications or various sensor fields. In addition, we describe comparison evaluation between conventional Ubiquitous computing framework and UbiMDR framework with data accuracy of interoperability.

  • SERA - Uniformly handling Metadata registries
    Software Engineering Research and Applications, 2006
    Co-Authors: Dongwon Jeong, Young-gab Kim, Soo-hyun Park, Doo-kwon Baik
    Abstract:

    This paper proposes a query language to consistently access Metadata registries. In current, many Metadata registries have been built in various fields. Unfortunately, there is no access method to access the Metadata registries in a standard manner. Thus many management systems have been developed in various and different access methods to build and manage their Metadata Registry. In this paper, we propose a Metadata Registry query language that allows us to access consistently all Metadata registries in a standardized manner. The query language is an extension of the standard query language for the relational databases SQL which is familiar to existing database managers. Consequently, the proposed Metadata Registry query language reduces the development cost of a Metadata Registry management system. And it also enables all Metadata registries to be accessed in a consistent manner.

  • SERA - A Framework for Application-Independent Semantic Management for Ubiquitous Computing Environment
    Fourth International Conference on Software Engineering Research Management and Applications (SERA'06), 2006
    Co-Authors: Dongwon Jeong, Jinhyung Kim, Yixin Jing, Doo-kwon Baik
    Abstract:

    This paper proposes a semantic management framework providing the ubiquitous application field-independent interoperability. The goal of the proposed framework is to provide a consistent and independent semantic usability to ubiquitous applications. The proposed framework uses the merits of the Metadata Registry that has been developed for exchanging and sharing between databases by ISO/IEC JTC 1/SC 32. The proposed framework allows application field free semantic management and enables the practical and ideal ubiquitous application development

  • UIC - Resolving the semantic inconsistency problem for ubiquitous RFID applications
    Ubiquitous Intelligence and Computing, 2006
    Co-Authors: Dongwon Jeong, Youn-hee Han
    Abstract:

    This paper proposes a noble RFID system architecture, named uRFID, to support application domain-independent semantic interoperability under ubiquitous environment. The objective of the uRFID is to let ubiquitous RFID applications independently use information of tags in a consistent way in a variety of application domains. Although many researches have been studying to support the RFID applications, they do not consider the aforementioned semantic inconsistency issue. The uRFID is based on the Metadata Registry to achieve the goal. It provides an infrastructure support for the semantic consistency and application domain-independent information utilization. As a result, it enables high quality RFID applications to be developed for ubiquitous environment.

  • SSDBM - Use of Metadata registries for searching for statistical data
    Proceedings 14th International Conference on Scientific and Statistical Database Management, 1
    Co-Authors: C. Nelson
    Abstract:

    The Internet has spawned an insatiable appetite for information. This appetite cannot be satisfied without useful search tools. These tools rely on Metadata in order to give targeted and meaningful results to searches, and the Internet world is realising that Metadata, its management, and the means to search these Metadata, are an integral part of the Internet world. The EC 5th Framework project COSMOS aims to demonstrate the use of Metadata in this way by building a common model for describing a statistical data set in terms of Metadata, populating a Metadata Registry with descriptions consistent with the model, and searching the Registry to find the data sets, and finally to access the data sets in the relevant repository.

  • IGARSS (5) - Evolution of web services in EOSDIS — Search and order Metadata Registry (ECHO)
    2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
    Co-Authors: Andrew E. Mitchell, Hampapuram Ramapriyan, Dawn Lowe
    Abstract:

    During 2005 through 2008, NASA defined and implemented a major evolutionary change in the Earth Observing system Data and Information System (EOSDIS) to modernize its capabilities. This implementation was based on a vision for 2015 developed during 2005. The “EOSDIS 2015 Vision” emphasizes increased end-to-end data system efficiency and operability; increased data usability; improved support for end users; and decreased operations costs. One key feature of the Evolution plan was achieving higher operational maturity (ingest, reconciliation, search and order, performance, error handling) for the NASA's Earth Observing System Clearinghouse (ECHO). The ECHO system is an operational Metadata Registry through which the scientific community can easily discover and exchange NASA's Earth science data and services. ECHO contains Metadata for 2, 726 data collections comprising over 87 million individual data granules and 34 million browse images, consisting of NASA's EOSDIS Data Centers' and the United States Geological Survey's Landsat Project holdings. ECHO stores Metadata from a variety of science disciplines and domains, including Climate Variability and Change, Carbon Cycle and Ecosystems, Earth Surface and Interior, Atmospheric Composition, Weather, and Water and Energy Cycle. ECHO provides a platform for the publication, discovery, understanding and access to NASA's Earth Observation resources (data, service and clients). In their native state, these data, service and client resources are not necessarily targeted for use beyond their original mission. However, with the proper interoperability mechanisms, users of these resources can expand their value, by accessing, combining and applying them in unforeseen ways. ECHO provides access to its capabilities through a set of services. These ECHO Applications Program Interfaces (APIs) are based on industry standards for performing web-based computing, specifically web services profile.
